Direct effects of tephra fallout on Nothofagus pumilio ring widths in northern Patagonia

We evaluated the radial growth response of adult Nothofagus pumilio (Poepp. et Endl) Krasser trees affected by tephra deposition following historical volcanic eruptions of the Puyehue–Cordón Caulle Volcanic Complex (PCCVC) in northern Patagonia. Standard tree–ring width chronologies were developed for trees from two sites that were affected by up to 55 cm of tephra during the 2011 eruption, which allowed us to detect the general tree–growth response to eruptions VEI ≥ 3 and VEI ≤ 2.

Teaching dendroclimatology to our educators and youth

Bryan Yockers and Lee Borzick were invited to participate in the Research Experience for Teachers collaborative research project by the Laboratory of Tree-Ring Research, funded by the National Science Foundation, and led by Irina Panyushkina and Dave Meko.

Upside down and the game of C allocation

Soluble sugars (e.g. glucose, fructose and sucrose) and starch are the most abundant components of the non-structural carbohydrates (NSCs) stored in woody tissues of the stem and roots. These compounds represent the most abundant C reserves in trees, contributing to plants survival and their resilience to adverse conditions. These compounds are involved in controlling and regulating photosynthate allocation between C supply and demand.

How trees can contribute to reconstruct the local pollution history and remove ultrafine particles from the atmosphere

Dendrochemistry has proven to successfully provide a temporal record of trace metal deposition from a variety of pollution sources. Trace element uptake by trees was mainly thought to occur by soil-root transfer but direct transfer of particulate matter from the atmosphere to the shoots is also possible. However, the physiological mechanisms involved in the uptake and transport processes of ultrafine particles is largely unknown. Their presence in the tree rings is still unexplored.

New ¹⁴C dating of Sintashta's largest worship structure—BSK: baffling story of one ziggurat that challenged the narrative of Middle-Late Bronze Age archaeology in the northern Eurasian Steppe.

Research on the sociocultural complexity of the Eurasian steppe in the Bronze Age has been challenged by recent advances in the prehistorical calendar chronology derived from high-precision AMS carbon-14 measurements. The medley of archaeological cultures in the Southern Urals on the border between Russia and Kazakhstan is distinguished in space with the prominent typology of ancient ceramic and burial traditions.
